Installation failes with error like “SQL Connection terminated by host”.
This can be due to TLS hardening on the management server, since the installation wizard cannot handle TLS 1.2.
Enable TLS 1.0 and 1.1 in the registry on the management server before starting the installation:
HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0
HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1
These two paths should contain a key called Server and another one called Client for each version.
And in each Server\Client key, two DWORDS:
DisabledByDefault=0
Enabled=1
There could also be an issue with the SQL it self, that it only accepts TLS 1.2.
